- Rename the `TestOutputDirectories` class because it is picked up by pytest as something it expects to contain tests
- Switch fields to using `Path`, rather than `str`
This PR reworks mypy_runner.py both to ensure all files are checked, and to speed up the process (from about 3 minutes to about 12 seconds in the PR build). Rather than processing one file at a time, mypy is called repeatedly with "--verbose" set, and the logs are (silently) checked to see if files have been visited. Visited files are excluded from the set to be checked, and mypy is invoked again on the remaining ones until there are none (or until no further files are visited - though this should not and does not seem to happen).
Care is taken to ensure that this script can also be called when this repo is present as a submodule (assumed to be called innereye-deeplearning as usual). When this is the case, we do not check the files inside the submodule, as we assume they have already been checked as part of the build process here.
It is also now possible to provide the script with a specific list of files to check, by supplying them on the command line.
Running this new version turned up a couple of previously undetected type issues, which are also fixed here.
